Hi, I am seeking a couple of ancient Fairchild uL926 rtl jk flip-flops to repair a frequency counter. Hoping someone has some old stock or pulls from an old logic board?? Original part number is uL92629. Anyone?
Hi Simon, there are two versions of this IC - a "glob top" epoxy round package or a squatter TO5 type package - either would be fine for me!

EDIT: I have seen this IC from two manufacturers - Fairchild (p/n FuL92629) OR SGS (p/n 5992629P)
I apologize for getting your hopes up but can not find any.
If I come across will send a pm.
Good luck

Many thanks Johnny - I think I will need to look at substituting a modern CMOS flipflop for the 926.
I am still looking, I know I had some years and years ago. I suspect the bad ones were in the front end and actually were higher speed than CMOS would be running at three volts.
There was also a flat pack version.

Hi Simon,
Thanks for getting back to me - if you had some that would be really appreciated! Cheers, Grant

A heads up that thanks to a generous member here at diyaudio I was given some uL923 ICs which got my old Advance TC11 counter back into operation. Thanks Jan!
